Just wanted some advice on removing my BB30 crankset as I am getting a squeaking sound and I want to clean and re-grease the BB etc. I can remove the drive side easily enough (just use a 10m hex key) but when I get to the non-drive side there is a washer kind of thing around the nut where I would insert the 10m hex key and written on the washer is "do not remove".. is this telling me I should remove that crank arm?? I will take a photo tonight and put it up to make it a bit easier to understand what I mean.

Has anyone else encountered this before? am I ok to remove the arm despite it saying not to on the washer?

My FSA cranks have only one hex nut on the non-drive side which you loosen to remove that crank arm, and then tap the shaft through the BB 30 bearings to remove the drive side. The cap on the non-drive side is there to cover/protect the hex nut thread and the end of the shaft from moisture/dirt etc as far as I understand it, and shouldn't come off when you loosen the nut.

The bearings are a different kettle of fish and are awkward to remove/replace without the correct tools, though not impossible. I've found that removing the cranks and even the chainrings for a thorough clean and reassembly solves most creaks and grinds anyway.

the cranks are sram force cranks, both sides have a hex nut opening and the drive side comes off so maybe I should just try and tap the shaft through, will have a look at this tonight thanks for the info

I also have sram cranks and all you need to do is undo the non-drive side and tap the shaft through with a rubber mallet. they are a 2 piece crank and therefore you dont remove the drive side crank from the shaft.
